Recently I have the need of study trace spaces of Orlicz-Sobolev spaces. By looking in google I have discovered in this PDF page 14 (not only in the PDF), that the main contributions come from the authors: A. Fougeres (1972), M-T. Lacroix (1974), G. Palmieri (1979). I tried to find the respective papers but with no result.
For example, the paper of Lacroix is: M.-TH. LACROIX, Espaces de traces des espaces de Sobolev-Orlicz, J. Math. Pures Appl. 53(9) (1974), 439–458.
So my question is: Does anyone know if I can find those papers on internet? Or, if there is some updated books or surveys which contains those results?
Thank you
